STOVE STRUCTURE;

'appiicaiion nieu January 15, 1925. seriai No. `2,505. I

To all whom it may concern:

Be it known that I, THOMAS E. TAYLOR, a citizen of the United States,residing at Mansfieldgin the county of Richland and State of Ohio, haveinvented certain new and useful Improvements in Stove Structures, ofwhich the following is a specification.

My invention relates to improvements in stove structures, the presentimprovements.

being particularly designed and adapted for use in connection with rangetype.` V

The primar;v object of the invention is t-he provision of an improvedfine and chamber forming structure above the burner box and below thecooking top portions ofthe stove or range, said structure being of boX-separate heat generatingl chambers.

A further and important object is the provision of a flue and chamberforming structure for the lcooking top portion of the stove or rangewhich will not only improve combustion at the burners through thesuppl)` of secondary7 air solely through the base portions of the fuelburners but -Will enable the latter to be mounted a relatively fixeddistance from the cooking top irrespective of 4whether such top is ofthe closed or of the open type, thereby enabling such different types:vof cooking tops to be used intei changeably.

A still further and 'important object is tlie provision of an improvedforni and arrangement'of heat insulated oven, together with an improvedform and arrangement of cooking top and oven fiues and portsl adapted toprovide amaximum amount of heat with a minimum consumption of fuel.

With the above mentioned and other ends" in view, the inventionVconsists 1n the novel,

construction, arrangement and combination of parts, hereinafterdescribed, illustrated gas stoves of the in some of its embodiments inthe accompanying drawings, and particularly pointedv out in theappendedclaims.

Referring to the drawings, forming apart of this specification, Figure'1 is a fragmentary perspective view of the burner box and heatingchamber portions of a gas range of the side oven type, constructed inaccordance with this invention, the cooking top section beine removedfor the purpose of clearer illustrationof the parts. y

showing a modified arrangement of the oven iiues and ports.

Similar numerals of reference designate like parts throughout all thefigures of the drawings.

While in the present instance I have shown my improvements applied to orincorporated iii a gas range of the insulated ifold pipe 2, beingconnected to the fuel burners 3, through the neck portions 3, in

the usual or conventional manner. The burners 3 may be of any suitableand convenient form being, in the present instance, of the ring typewith a large central opening 3,

for the passage of secondary air upwardly from theburner boX l.

. -As a means of forming suitable flues and heat generating chambers andproviding for the proper location and combustion with re-.

spect to`secondary air,- a suitable flue and chamber forming structureis interposed between the burner box land the cooking top, saidstructure, inthe present instance, being in the speciiic form of a panor box-like structure consisting of a bottom section 4, and sides andends 4a and 4b arranged, in the A present instance, within the top framelu and divided into separate compartments by means of apartition'tc` Thecompartments forinseparate heat generating chambers 'beneath thecookingvtop section and as a means of supplying secondary air solely toand through the base portions ofthe burners 3, the bottom portions ofthe flue and chamber forming structure are provided with burnerfrom thefuel burners through the heat gen-- erating chambers to the ports 4e andinto the cooking top flue 4f at the rear, the flue' 4f passing, in thepresent instance, over to the rear wallof the insulatedoven to cooperatewith the fiu'es and ports of such structure, as hereinafter referredto.-

' When a cooking top of the closed or solid` type, such as the solid toptype 5, is used and as shown in Fig. 2 of the drawings, it will beapparent that relatively large unobstructed areas are provided beneaththe cooking top and which are adapted to be heated by the products'ofcombustion passing backthrough the heat generating chambers and beneaththe cooking top section, the burners 'being mounted at the front andremote from the outlet ports 4e for the products of combustion. Ifdesired, however, a simmer burner 3, may be provided at one side andeXtending through a burner receiving opening 3" for the passage ofsecondary air, but in such instance, it will be observed, that the topof the burner 3 extends flush with the bottom portion of the'iiue orchamber forming struc- Q ture like the main fuel burners 3, thereby notobstructing the passage of the products of combustionthrough-thechambers and beneath the relatively large area of the closedcooking top section above referred to.

The arrangement of the chamber forming structure with respect to therelative disposition of the burners and the secondary air or open typemay be used interchangeably without raising or lowering the burners,asis now common practice with the ordinary forms'of burner boXand-burner construcztion;

` In Fig. '3 of the drawings a cooking top of 75 the open or sectionalgrate type 6, is provided and, iii the present instance, as a convenient means of removably mounting and supporting the pan shaped orchamber forming structure, the upper marginal edges of ,80'

the side and end walls 4a and i?, respectively, are provided withoutwaldlyr, extending flanges 4g, adapted to rest on the inner inarginaledges of the cooking top frame la.

The cooking top flue 4f extends horizon- 55 tally into one side andbetween the inner and outer walls of theheat insulated oven 7, and 7,respectively, forming a common iiue for receiving the products ofcombustion arising from the burnersin the cooking top and the ovenburner 8, as now described. The side or glider members 9, within thesides of the baker oven and extending upwardly from the oven bottom l0,afford side flues 9a, within theoven and communicating between thebroiler and bakeroveiis. The products of combustion thus pass upwardlythrough the flues 9a and into the upper portion of the baker oven andare thence conducted downwardly and rearwardly to the port 11 in therear wall and near the bottom portion of the oven, said port l1intersecting the end of the rear oven flue, the flue port l2 beingoff-set to the side of the port l1 and the Hue port l2 being covered bya pipe, or elbow 13,-'at the rear as a common discharge port for thecooking top burners and the oven burner.

As a means of heat insulating the walls of the baker and lbroiler ovens,the inner and outer walls lTand '6L res Dectivel n are ro- 110 a l .i P

vided with an interposed heat insulating filler material Tb, of mineralwool, or the like. The spaced walls of the oven being 4thus insulatedless heat is radiated from the walls than in the ordinary non-insulatedN5 cally entendingoven flue li, intcrsected near 125 the upper and lower'rear portions of the oven by means of port openings 14a and 14C",respectively.
